HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 243,864, dated July 5,1881. Application filed March 24, 1881. (No model.)

To all whom it may concern:

Be it known that I, MIOHAEL DILLMEIER, of Brooklyn, in the county ofKings and State of New York, have invented a certain new and usefulImprovement in Hose-Gouplin gs, of which the following is aspecification.

When the ordinary hose-couplin g, the female part of which consists of ahorn-band with an internal screw-thread, is thrown down and the portionof the band between the horns strikes hard upon the pavement or otherhard surface, there is liability of the band being knocked outof shapeand of the screw-thread being thereby so injured as to prevent the maleand female parts from being readily screwed to together or unscrewed onefrom the other; and the object of my invention is to provide a couplingin which there shall be no such liability.

To this end my invention consists in an internally screwethreadedhorn-band for a coupling having rigid horns projecting therefrom, andmade in the same piece therewith, and also having between said hornsprojecting guards, which are formed in the same piece with said band,and greatly increase the thickness of metal at the points which arelikely to be struck, or upon which the coupling is liable to strike, andto which a wrench may be applied for unscrewing the coupling in case thehorns become broken off. The said guards are preferably V-shaped orbeveled upon opposite sides toward the ends of the coupling, wherebywith the same amountof metal a much greater projection of the guard isobtained and a more effective protection for the internal screw-threadis afforded, as the blow or striking point will be upon the edge of thean gular or V-shaped guard.

In the accompanying drawings, Figurel represents a side view of aportion of a coupling with an attached hose, and which embodies myinvention; and Fig. 2 represents an end view thereof. 7

Similar letters of reference designate corresponding parts in both thefigures.

A designates the horn-band of an ordinary coupling, which is internallyscrew-threaded, and from which project two horns, a, in oppositedirections.

Between the horns a, and upon opposite sides of the horn-baud A, areprojections b, which are shown as projecting nearly as far from theexterior surface of the horn-band A as do the horns a; and, as-clearlyshown in Fig. 2, these projections extend nearly the whole distancebetween the two horns a and form guards for the horn-band. When thecoupling is thrown down, if it did not strike upon the end of one horn ait would probably strike upon one of the projections b; and even if thecoupling were thrown down and should strike hard upon a pavement orother hard surface, the screw-thread would not be liable to be injuredso as to interfere with the screwing together or the unscrewing of theparts of the coupling, because of the great thickness of metal formed bythe projecting guards. Both the horns c and guards b are, of course,formed in the same piece or casting with the hornband.

It will also be observed that when the band A is let fall its open mouthor screw-thread is supported considerably above the ground, and there islittle liability of dirt getting into the screw-thread. This is clearlyshown in the drawings, in which 0 represents the surface of the ground.

It will also be seen by reference to Fig. 2 that the projecting guards bare of such a form at their ends that if the horns a should be brokenoff a monkey or screw wrench could be easily applied to the projectionsto turn the band A.

The projecting guards b are preferably V- shaped or their sides arebeveled or slanted from the middle of the width of the horn-band Atoward the opposite ends of the coupling, and when so formed an equalamount of metal will give a greater projection of the guards b, and willtherefore give greater protection.

WVhen lengths of hose are to be coupled or uncoupled in a hurry, aswhile extinguishing a fire, it is of the utmost importance that thecouplings should bein perfect order, and by my invention I obviate theliability of the female screw-thread being injured.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A horn-band for a screw-coupling, having guards projecting therefrombetween the the V-shaped or beveled guards b, substanhorns, both saidguards and hornsbeingformed tiall y as described, and for the purposeset in the same piece or casting with said band and forth.

forming rigid projections thereon, substan- 5 tialiy as and for thepurpose specified. \Vitnesses:

2. The horn-band A of a coupling, having FREDK. HAYNES, the horns a, andalso having between the horns ED. GLATZMAYER.
